If you're considering installing an EV charger for at-home charging, there are several factors to keep in mind, from choosing the correct charger to understanding installation costs and maintenance. This guide will walk you through everything you need to know to make an informed decision.

Types of EV Chargers and Charging Levels

Level 1 Chargers:

There are three types of EV chargers, each with advantages and disadvantages. Level 1 chargers are the most ubiquitous and the most affordable. These chargers can be plugged into standard home outlets (120V) to charge an EV. The tradeoff is charging speed, with level 1 chargers only being able to add 3-5 miles of range per hour. That's not much if you're empty and charging overnight—which is why these chargers tend to work best for plug-in hybrids since they aren't solely battery-dependent.

Voltage: 120 volts (standard household outlet).
Charging Speed: Adds about 3–5 miles of range per hour.
Best For: Occasional or low-mileage drivers who can afford longer charging times.
Installation Requirements: No additional equipment or electrical work needed.

Level 2 Chargers

Level 2 chargers are a massive upgrade that requires a 240V circuit — i.e., the type of circuit that powers large electric appliances like ovens and dryers. While this often requires professional installation, the benefits are hard to ignore. A Level 2 charger can charge at an average of 20 to 30 miles of range per hour. Depending on the type of charger and EV, that number can go up to ~45 miles of range per hour. Installing a hardwired Level 2 charger is recommended to maximize the charge rate.

Voltage: 240 volts.
Charging Speed: Adds 20–30+ miles of range per hour.
Best For: Daily drivers or households with multiple EVs.
Installation Requirements: Requires a dedicated 240-volt circuit, ideally hardwired and professional installation.

Level 3 Chargers

A Level 3 charger is impractical for home use due to the significant infrastructure requirements and cost. Also known as DC fast chargers, level 3 chargers are incredibly efficient, charging an EV's battery up to 80% from empty in under 30 minutes. While over-relying on level 3 fast chargers can eventually degrade the battery due to the heat produced by a faster charging rate, they are great for planned use or in a pinch. Long road trips would present a challenge without DC fast chargers.

It's a good idea to consider everything from where you're parking your EV to accessibility and weatherproofing the charger. For instance, if you predominantly park your EV in your garage, installing a level 2 charger is a simple and practical decision. Proximity between the charger and the EV preempts the need for an extra-long cable. However, charger placement may require a bit more planning if you only have street parking or if you park other vehicles in your driveway or garage.

When installing your EV charger inside your garage, consider the distance between your vehicle and the charger for optimal convenience. If you have a double garage or multiple EVs, positioning the charger in a central location ensures the charging cable can easily reach both cars. A well-placed charger provides flexibility and minimizes the need for costly extender cables or frequent repositioning.
